I got into this situation where I play the arranger (drum rythms only, left bass, right piano/strings) and the other guy played the bongo or something like that, tall double cylinders type. The person sat next to me and play her heart out. No matter how loud I turn up the keyboard, I still could not hear the drums on the kybd. All I hear is the bongo rythms. And after a while we both gets out of sync. The arranger drums goes one way and the bongos goes the other and I end up following the bongos. It was a big mess and a big headache. Anybody experience this and know how to resolve it.
